Enum Definition 

pub enum Definition {
    Formula(FormulaText),
    Sql {
        target: Name,
        query: String,
    },
    Call {
        target: Name,
        func: String,
        args: Vec<Name>,
    },
    Lambda(LambdaText),
}

A parsed measure definition — either an ordinary formula or a source form (SQL("...") / CALL(fn, m1, m2, ...)) that describes a host-side source rather than a differential-dataflow expression. Source forms carry the metadata a refresh consumes; they never enter the engine’s expression graph, preserving the deterministic core.

Variants

Formula(FormulaText)

Target = <expr> — an ordinary engine formula.

Sql

Target = SQL("<query>") — a SQL-sourced input measure. The query is the raw string; column→dimension mapping is the caller’s concern.

Fields

target: Name

query: String

Call

Target = CALL(func, arg_measure, ...) — an external-function measure. func is the registered function name; args are the argument measure names (resolved to ids by the caller against the model).

Fields

target: Name

func: String

args: Vec<Name>

Lambda(LambdaText)

Name = LAMBDA(p, …, body) — a named LAMBDA (Excel’s Name Manager), callable as Name(args) in formulas once added to the model.
